1/n There is a new devnet update coming to @AptosLabs , and it's huge (same as a few recent updates 😎). Here is a thread.
@AptosLabs 2/n Default table::Table doesn't have length anymore. For a table with size, use the new module: table_with_length::TableWithLength.

Word of the day: 𝗔𝗺𝗯𝗶𝘁𝗶𝗼𝗻
Steve Jobs said once : "Start small and think Big and you'll get Big."
Today I bring you a full thread on the most ambitious Layer 1 @Aleph__Zero $AZERO and the most ambitous projects building on top, you may want to spare some time to read 👀👇
To start with you need to know that @Aleph__Zero $AZERO is an enterprise-ready #blockchain with built in privacy through ZK-SNARKS (Zero Knowledge Proofs) & sMPC (Secured Multi Party Computation) this will open the #Cryptosphere to Companies and SME's to onboard the space, Why?👇
Start small, think big is exactly what @Aleph__Zero is doing as one of the very few #blockchains to be enterprise-ready and the only one to implement Privacy-enhanced feature to the #SmartContracts launching soon, this will enable companies and sme's to preserve sensitive data 👇

👀🔸 ¿Qué son los EIPs? Los Ethereum Improvement Proposals se utilizan para informar a los usuarios y proponer nuevas funcionalidades en #Ethereum
🔸 Cualquiera puede proponer nuevas funcionalidades, pero no todas las propuestas son admitidas por el equipo de desarrollo de Ethereum.
🔸 Un ejemplo sería el EIP-214, realizado por el mismísimo Vitalik.

El EIP-214 añade un nuevo opcode para aumentar la seguridad en los #smartcontracts

[#THREAD] Intéragir directement avec un Smart Contract

Difficulté technique : ★☆☆☆☆

Mint sans passer par une dApp, transférer un NFT, on a plein de raisons de vouloir intéragir avec un Smart Contract.

Mais comment faire ?

#Web3 #SmartContracts #NFT #Crypto

⬇️ Image
Interagir en direct avec un contrat a beaucoup d'avantages.

Notamment lorsqu'une #dApp ne fonctionne pas ou ne propose pas certaines fonctionnalités comme le transfert par exemple.

Cela va nous permettre d'avoir accès à toutes les fonctions publiques et externes !

> Le scope

Aujourd'hui je ne parle que des contrats qui sont déployés sur Ethereum et toutes les EVMs (AVAX, BSC, Fantom, Polygon, etc..)

Ce qui couvre déjà une belle partie de notre écosystème !

En contextos de tanto escepticismo por la aparición de tecnologías disruptivas (léase #blockchain, #cryptocurrency, #bitcoin, etc.), quiero traer uno de los tantos casos de grandes cambios tecnologicos que generaron un antes y un despues en la historia. Mini hilo 🧵
Rondando el año 1200, los templarios diseñaron el "disruptivo" sistema de CHEQUES, utilizado hasta el día de hoy por todas las organizaciones bancarias del mundo. El mismo tenía como objetivo reducir riesgos y dificultades asociados al transporte de grandes volumenes de dinero. Image
En vez de tener que transportar kilos de monedas/oro, con estos papeles se podía retirar cierta cantidad de dinero en los bancos pertenecientes al movimiento... tal cual hoy en día. Riesgos de esto? Fraude en los documentos, ente central regulador, entre otros.

Notre objectif est de rajouter et modifier certaines caractéristiques :

• Ajouter des étapes de vente.

How to use rewards from @NEARProtocol
🧵 👇
@NEARProtocol @NEARProtocol allocates 30% of transaction fees to the #smartcontracts these transactions touched

🤑

popular libraries can receive a flow of funds from all the client applications that are using them
@NEARProtocol funds can be kept on the #smartcontract to allow it to allocate more storage space

🤑

#DAO managing this application can decide what to do with these funds

third-party can use buy-back & burn mechanics for contracts that have their own token

TRYING TO EXPLAIN #DEFI TO MY MOTHER

I'm on a mission to help onboard as many "normies" possible into the world of DeFi

It requires choosing the right words & analogies to help explain technical concepts

So heres a 🧵 I hope you find helpful you can send to your own normies 👇
First, let's start with concepts we understand.

INCENTIVES. The world revolves around them. Everything anyone tries to get someone else to do involves incentives.

I mean, what is dessert for a child if not a bribe to finish dinner?

🧵/2
The world of finance is no different.

What bank do you open a savings account with?
Probably the one offering the highest APR (incentive).

What bank do you have a checking account with?
The one with cashback rewards, or lower fees, etc.

[#THREAD] On créé un contrat ERC721 pas à pas

Difficulté technique : ★★★☆☆

Dans mon dernier thread on a découvert certaines fonctions d'ERC721.

Aujourd'hui on va créer notre premier contrat NFT ensemble !

#Web3 #Solidity #SmartContracts #NFT #Crypto

⬇️

1/18
Notre objectif est de réaliser un contrat ERC721 qui a pour caractéristiques :

• Une supply (nombre de NFT) de 100.
• Un prix de 0.00001 ether (🐀).
• Permettre de mint plusieurs NFTs d’un coup.
• Permettre de récupérer l’argent du smart contract par le propriétaire

Je vous conseille fortement de suivre directement ce thread avec le code que j’ai déployé sur mon Github :

[#THREAD] Les fonctions de #ERC721

Difficulté technique [4/10]

On utilise au quotidien la norme #ERC721 apparue en janvier 2018.

Mais connaissez-vous toutes les fonctions qu'elle embarque ?

On va regarder cela ensemble

Je vais parler exclusivement des fonctions que vous pouvez appeler en tant qu’utilisateur et non les fonctions internes à la norme ERC721.

Mais si vous le souhaitez je ferai un autre Thread qui détaille davantage tout le fonctionnement de cette norme !

(1/19) Crypto 101: Wallets

What actually is @MetaMask? Is my $ETH inside my @Ledger? Why does everything involving crypto have to use a wallet?

A very high level discussion of #cryptography and #smartcontracts
(2/19) Do you ever wonder why this whole thing is called “Cryptocurrency?”

There’s a lot of things Satoshi gave us, but critical to everything are the properties of cryptography.
(3/19) Number Theory was the hardest class I’ve ever taken. Just trust me, the “Operation” section of this Wikipedia page mathematically proves this truth of cryptography:

You can create private messages between two parties over a public network.

Top of the morning to all.
Some newer investors may not know this (I know...I've seen it mentioned in Discords) but we don't actually HAVE to interact with #smartcontracts using a website.

We can use the #blockexplorer. Here's a thread for newbs on how.

🧵/1
First...why would you do this?
Well, #crypto is full of paranoid skeptics (understandable given all the rugs) so when a site goes down and people can't access the buttons for claiming rewards it's INSTANT PANIC 🚨

🧵/2
The thing is, smart contracts are immutable, and unless the developer uses a kill function, it's still going to function, with or without a website.

And you can access those functions from the appropriate block explorer (based on the chain the contract is on).

🧵 A dose of reality on shitcoin triablism: Had a tough couple of weeks in the market, as have many. Today I had a good day and I'm happy with that. I also saw a lot of things that made me sad and and wanted to share a few thoughts. 1/12
I got into crypto in 2017 primarily because I thought #smartcontracts on #Ethereum sounded interesting. I'd heard of $BTC but wasn't honestly never thought the use case would catch on - yeah I legit thought about use cases back in the day 😆 2/12
Long-story short at first I was fascinated by the technology and potential of #blockchain but it didn't take me long to get sucked in by quick riches, ran 4 figs up to 6 figs pretty quick, was planning my retirement (lol) and then got totally rekt in the bear market. 3/12

👀 Sabias que en un contrato ERC-20 una cuenta ajena puede enviar tokens de tu propiedad a otra dirección? 🤯 Whaaaat ... ?!

🧵⬇️ Te explico cómo en el siguiente hilo:

#smartcontracts #ethereum
La cuenta (spender) que quiera enviar los tokens en tu nombre, solo tiene que llamar a la función "transferFrom" del smart contract con los siguientes parámetros:

🔹 Cuenta origen (address _from) ℹ️ La tuya
🔹 Cuenta destino (address _to)
🔹 Cantidad de tokens (uint256 _value)
😌 Pero tranquis, esta función SOLO podrá ser ejecutada satisfactoriamente si antes le hemos dado permiso al "spender" de enviar esa cantidad de tokens.

Nota mental: 😬 No os fieis nunca de esto. Si veis una función "transferFrom", desconfiad y chequead el código.

¿Qué hace que un smart contract sea ERC-20? 👀

“Si un contrato inteligente implementa los siguientes métodos y eventos, se puede llamar un contrato ERC-20”

Abro hilo para explicar cada método y evento.

Dentro hilo! 😜

ethereum.org/es/developers/…

#SmartContracts #Ethereum
🔹 "function name() public view returns (string)"

Esta función nos devuelve el nombre del token. Por ejemplo: Dogecoin.
🔹 "function symbol() public view returns (string)"

Esta función nos devuelve el nombre corto del token. Por ejemplo: DOGE.
